To all whom it may concern.'

Be it known that I, CLARENCE R. Nansen, a citizen of the 'United States, residing at Yonkers, in the county of Viestchester and State of New York, lhave invented certain new and useful Improvements in Heaters for Automobiles af following is a full'and clear specification.

My invention relates to heaters for automobiles, motor boats, or the like, and par ticularly to heaters which utilize the heat eener-ated by the fluidpressure engine which drives the automobile or the like.

One object of my invention is to provide means for utilizing the heat generated by the engine to keep at any desired temperature a plate set in the floor of the tonneau or pas senger-carryin g. compartment.

An additional object isto simplify the construction and operation of devices of this character, and to increase their eflieiency.

Referring to the drawings in. which l have illustrated my invention,|as applied to an automobile, Figure l is a plan vieuT of my device showing diagrammatieally its relationto the chassis and body of an automobile; Fig. 2 is a plan View of my device with the top of the drum removed; Fig. 3 is a side elevation, and Fig. Il is a detail of a pipe union and valve.

l represents the exhaust pipe of any fluid pressure engine which eXpels `eases or vapor at a temperature considerably above atmospheric temperature. it E2 the exhaust pipe is branched to provide two courses for the exhaust gases. The branch 3' leads to the inuiiler et in the usual manner. .lhe branch 53 leads to the rectangular or box shaped drum 6, hereinafter referred to, and thence through the outlet 7 to the mul'ller eiln .the union :1t-2 l have placed a three way valve` 8. Whose position determines the course of the exhaust `gases through one or the other of the branches 3, 'flhe valve 8 is operated by the right angled lever S) which projects above the Hoor of the tonneau within easy reach of the orcupants of the tonneau. The drum (3 is made pietra-ably of cast iron of any suitable thickness and can be of any dimensions consistent with .the space available. Within the drum 6 l have placed the vertical rightangrled partition l0, which exteni'ls from a point in the side of the drum between the inletll and the outlet i', to apinfoxiiuately theI middle of the drum and thence, .longitiuliually to a point short Speeficatonof' :tet ters Patent.

rof the end of the drum. The partition 10 is of the saine depth as the drum G and compels the hot gases which enter at 1l to trav-- erse the whole space inelosed by the sides of the druin before goingfout at 7. It will be noted that the inlet land outlet ports are placed as close together as is practicable and in that part of the drum which is nearest to the exhaust pipe. This arrangement of the inlet and outlet ports enables me to connecty as to obstructthe direct passage of the gases from the inlet to the outlet. l

iliccording to the preferred construction of the drum 6, it will consist-ot tivo eastings, a lower casting;h comprising' the bottom, vertical sides, and partition; and an upper or top casting which consists ofp a plate adapted to form a panel in the iloor of the tonneau and which -can be corrugated or scored on its upper surface to prevent slipmug. v

The location of the drum in the floor of the tonneau is capable of variation. The preferred position is ilhlstrated 'in Fig. `1 where the top plate is seen lto extend almost arr: s the ear and in convenient relation to the seat to enable the imssengers to lace their feet on the plate. The sides oI the lower casting` are bent outwardly at the top (see Fig. Bl to form a flange l2. The flange l2 provides means for fasteningtlie top plate to the lower castingV and for supportiup; the drum in position.

'ihe use of in v device is not limited to automobiles, but is adaptable to motor-boats or iu ronneetion with a fluid pressure en- ;fine wherever used.

ln an automobile heater the combination of an exhaust pipe,I a drum arranged with one end adjacent the eXliai.1st-}"ipe, said I drunl being" provided with a. partition havioo intr one portion extending longitudinally of the drum and terminating near the far end thereof and a portion extending ktiransthe said partition and a Valve for governing 'versely of the drum and ternunatlng at one the flow of exhnust @ases througl'i Said drum. side adjacent the opposite end thereof, and
